ApplicationSeptember 6, 1933, Serial No. 688,348 7 Claims. (01. s-1)' Thisinvention relates to a machine for clamping frames on pocketbooks.

The object of the invention resides in the provision of a machine bymeans of which frames 5 may automatically be clamped on the edges ofpocketbook bodies. 7

In the drawings:

Fig. 1 is a side elevation, partly in section, of a machine constructedin accordance with my 10 invention;

Fig. 2 is a horizontal sectional view of line 2-2 of Fig. 3;

Fig. 3 is a vertical sectional View of a portion of the machine;

Fig. 4 is a vertical sectional View on line 44 of Fig. 2; and

Fig. 5 is a perspective view illustrating the type of pocketbook onwhich the machine is adapted to operate.

frame 1 is attached to the body portion 2. This frame 1 is U-shaped incross section as shown in Fig. 3 and the sides are pivoted together asat 3. The upper edge 4 (see Fig. 3) of the .pocket- 5 book body 2 isclampedbetween the flanges of the frame 1.

The machine of this application is adapted to tuck the upper edges ofthe body f the pocketbook between the flanges of the frame 1 and toclamp the flanges onto saidso tucked edges of the body of thepocketbook.

The machine consists of a frame 5 which supports a seat 6 for thepocketbook body 2. This seat 6 is provided with a recess 7 ofsubstantially the same shape as the body of the pocketbook 45 face plate8.

when the latter is open. This seat carries a face plate 8 on one side ofwhich is mounted a fixed abutment 9 andon the other side of which ismounted a movable abutment 10. A retaining plate llhaving a bevellededge 12 is adapted to urged inwardly by a spring 17 to cause thebevelled edge to overlie the adjacent flange of the pocketbook frame.This spring 17 operates between a protrusion 18 on the retaining plate14 and a protrusion 19 on the abutment 10. A cam 55. 20, pivoted at 21in permanent relation to the In pocketbooks of the type shown in Fig. 5a

seat 6 by means of a bracket 22, operates against the protrusion 19 andis controllable by handle 23. A link 24 pivotally secured at 25 to there taining plate 14 is pivotally' and slidably secured to the cam 20 bya set screw 26.

A plunger 27 of the general shape of the pocketbook body 2 and on whichthe body is adapted to be secured by means of pins 28 is mounted on arod 29 which is slidably mounted within an inner shaft 39. This shaft isremovably attached at 31 to the main shaft 32 that is operated bytoggles 33, which toggles are actuated by means of a treadle 34 througha connecting link 35 and a bell crank lever 36.

The plunger 27 carries a plate 37 on its upper face beneath which plateare slidably mounted a plurality of tucker blades 38. These blades 38are connected to the inner shaft 30'by means of links 39 which extendthrough slides 40 in the plate 37.

I A punch 41 ismounted rigidly on themain shaft32. This punch carries,within itself, pivoted latches 42 that are normally'held in engagementby means of springs 43 with stationary latch elements 44.-carried by theplate 37. The en' gagement of these latches 42' with the stationarylatch elements 44 maintains the punch 41' and the plunger 27 stationarywith each other.. Each.

of these latches 42 has an arm 45 extending therefrom which armprotrudes through the punch 41' and supports the inner end of a lever 45(see Fig. 1) which lever is pivoted at 46 to the punch 41. At theopposite end of the lever is an extension 47 and slightly inwardly fromthe extension a downwardly protruding projection 48. The upward movementof the inner end of this lever is limited by a'stop 49 carried by thepunch.

Below each of these levers 45. is a trip 50 which.

is pivoted at 51 and the upper end of which is urged into the path ofmovement of the extension 47 of the lever 45' by a spring 52.

The plunger 27 is normally urged away from the punch .41 by springs 53toward the position shown indot anddash lines in Fig. 4, which springscome into operation when the latches 42 are disengaged from the latchelements 44.

In operation the cam 20 is first operated by means of the handle 23 towithdraw the abutment 10 and the retaining plate 14 from the positionshown in Fig. 3. The pocketbook frame 1 is then put in place as shown inFig. 3 and the cam returned to its original, position whereupon theabutment 10 and the retaining plate 14 assume the position shown in Fig.3 and holdthe frame in place on the face plate 8.

Assuming the parts in the positions shown in Fig. 3, which positionsthey occupy before the sequence of operations is started, the pocketbookbody 2 is placed upon the plunger 27 in the position shown in Fig. 3,being held on the plunger by the pins 28. As the treadle 34 is actuatedthe shaft 32 is moved downwardly. The initial movement of the shaft israpid due to the small angle of the toggles 33 but the rapiditydecreases as the shaft moves downwardly and as the angle of the toggles33 increases. Thus the plunger 2'7 is initially moved rapidly toward theseat 6 but as it approaches the seat 6 it is more slowly moved. When theprojection 47 of each of the levers 45 engages the upper end of the trip50 the lever is moved about its pivot 46 and moves the outer end 45 ofthe adjacentl'at'ches 42' downwardly to disengage the latches from thelatch elements 44 against the tension of the spring 43; Immediately uponthe disengagement of the latches 42 from the latch elements 44thesprings 53 move the plunger 27 downwardly independents ly of and awayfrom the punch 41 into position shown in dot and dash lines in Fig. 4. g

During this movement the downward projection 48 of each of the levers 45engages the adjacent trip 50 and moves it into the dot and dash lineposition shown in Fig. 1 so that the lever 45 may return toits-initialposition under the influence of the spring 43. i

As the downward movement of the shaft 32 continues the plunger 27 seatsthe pocketbook body within the recess 7 so that the upper edges 4 of thepocketbook body project slightly. above the frame 1-. After the plungerand pocketbook body reach these positions the downward movement 'of theplunger ceases and the compression of the springs 53 begins. However,the downward movement of the punchcontinues under the influence of thetreadle. When the punch 41 arrives at a position just above the frame 1the links 39 assume a horizontal or dead center position. As the links39 approach the horizontalor dead center position from the dot and dashposition shown in Fig. 4 the tucker blades 38 are moved outwardl'yandengage the inner faces of the pocketbook body adjacent the upper, edge.As the links 39 continue to approach the horizontal or dead centerposition the blades face the edges of the pocketbook body between theflanges of the frame 1 and when the links assume the horizontal or deadcenter position they have completed the tucking action.

- The a continued downward movement of the punch 41 moves the links 39from their horizontal or dead center position toward and into theposition shown in full lines in Fig. 4, thus withdrawing the blades frombetween the flanges of the frame 1. At the time the withdrawal of theblades is completed the punch 41 has engaged the bevelled faces 16 ofthe retaining plates 11 and 14 and moved them outwardly against thetension of the springs 13 and 17 and has reached such a position that itengages the upper flange of the frame 1. The continued downward movementof the punch 41 depresses the upper flange and clamps the edges of thepocketbook body between the upper and lower flanges. During thisclamping action the latches 42 and the latching elements 44 again engageand under the influence of the main shaft 32 the punch 41 and theplunger 27 move upwardly as a unit into position fora repetition of thecycle of operations. a

While I have illustrated and described a particular embodiment of myinvention it is to be understood that I do not wish to be limited tothat embodiment but that I may make various changes in the details ofconstruction without departing from the spirit of the invention or fromthe scope of the claims.
